Generally, you make a capital loss if your reduced cost base is greater than your capital proceeds. The excess is your capital loss.
Example 14: Calculating a capital loss - Antonio
Antonio acquired a new income-producing asset on 28 September 1999 for $100,000, including stamp duty and legal costs. He sold it for $90,000 in November 2011. During the period he owned it, he was allowed capital works deductions of $7,500. Antonio works out his capital loss as follows:
Cost base  | 
$100,000  | 
less capital works deductions  | 
$7,500  | 
Reduced cost base  | 
$92,500  | 
less capital proceeds  | 
$90,000  | 
Capital loss  | 
$2,500  | 
Example 15: Calculating a capital loss - Chandra
In July 1996, Chandra bought 800 shares at $3 per share. He incurred brokerage and stamp duty of $100. In December 2011, Chandra sold all 800 shares for $2.50 per share. He incurred brokerage of $75. He made a capital loss, calculated as follows:

However, the reduced cost base is not relevant for some types of CGT events. In these cases, see appendix 1 for the amounts to use for the particular CGT event.
